Los Angeles - Britney Spears and Rihanna triumphed at the 2008 NRJ Music Awards on Saturday.
Britney, who has had a tumultuous time since divorcing Kevin Federline and losing custody of her two sons, saw off stiff competition from Rihanna and Amy Winehouse to receive the International Album of the Year prize for her comeback LP Blackout.
Although Rihanna lost out on the album award, her popular dance track Don't Stop the Music was named International Song of the Year at France's most famous music awards ceremony.
The stunning 19-year-old singer showed off her new short hairstyle as she performed her award-winning song at France's Palais des Festivals de Cannes.
SexyBack singer Justin Timberlake won International Male Artist of the Year, while Canadian star Avril Lavigne was crowned International Female Artist of the Year.
Amy Winehouse, who was nominated for International Revelation of the Year and International Album of the Year, was due to perform at the star-studded ceremony but was forced to pull out after entering rehab for drug addiction last week.
Lebanese-born Grace Kelly singer Mika, who wore a shocking pink jacket to the ceremony, picked up the International Revelation of the Year.
Michael Jackson, Celine Dion and Kylie Minogue all received the NRJ Award of Honour for their contribution to music.
